Three hundred British fans will get the chance to have David Tennant and Freema Ageyman sign their Doctor Who Series 3 boxset DVDs on Monday, November 5 at the HMV shop at 150 Oxford Street, London.
  The signing will be at 1:30 in the afternoon, but in order to be eligible, interested fans must pick up a wristband when the store opens at 9:00 a.m.  Only DVD sets can be signed. HMV notes that wristbands are one-per-customer and available on a first-come, first-served basis.

The boxset will be available in America on November 6, although Amazon.com appears to have already mailed pre-ordered DVDs.
